Anesthesia in the Hair Graft?
Anesthesia is one of the most relevant advances for the development of the surgical procedure, in hair transplant the most used anesthesia is local.
Feeling pain it is a complex phenomenon, which is undesirable for most patients. Some of the cosmetic procedures routinely performed are associated with varying degrees of pain. A variety of medications designed to combat pain have been developed. The most frequently used are anesthetics, pain relievers such as non-steroidal anti-inflammatories, and opiates.
Most patients who undergo hair transplant surgery have two main concerns: result to be obtained with the procedure and if there will be pain during or after surgery.
When a patient experiences pain during the recovery period, the patient will be left with a negative idea of the procedure and will hesitate to perform other medical procedures in the future.
Therefore, one of the goals that doctors have is to try to reduce pain as much as possible. When a doctor manages to minimize the presence of pain during the procedure, the patient will have a more benevolent recovery.
To a hair transplant procedure most doctors choose to use Anesthesia local, then the patient remains conscious during the procedure and this allows the procedure to be performed in a ambulatory. In order for the procedure to be carried out smoothly, anesthesia that works for long periods of time is required.
Ideally, in addition to sleeping the work area so that the patient does not feel pain, an anesthetic that is capable of reduce bleeding and increase the tumescence of the donor and implant areas to facilitate the extraction and implantation of the follicles respectively.
Most surgeons use a mixture of lidoicaine with epinephrine. The anesthetic effect of this mixture lasts around 4 hours. This type of anesthesia is particularly useful in short procedures. In longer surgeries it is required to use long-lasting anesthetics such as bupivacaine, which produces an anesthetic effect of up to 8 hours.
Anesthesia in the hair graft in the donor area.
Two types of anesthesia are generally used:
La main anesthesia, which serves to sleep the area of the scalp that is going to work. The main anesthetic is injected at the level of the dermis and subcutaneous tissue approximately one centimeter below the donor area. The maximum effect is usually reached 5-10 minutes after application, although it depends a little on each patient.
La tumescent anesthesia, which serves to facilitate the surgeon's work. The objective of tumescent anesthesia is to increase the tumescence of the tissues, increasing the distance between the follicles and the blood vessels and nerves. Therefore, bleeding and the feeling of discomfort are reduced. In addition to increasing the strength of the tissues facilitating the extraction of the follicles.
Anesthesia in the capillary graft of the recipient area.
Yes, implant the follicles It is also required to sleep the area where they will be placed. The anesthesia used also contains a mixture of anesthetics. It infiltrates locally, approximately 1 cm below the limit of the area to be implanted. It takes approximately 10 minutes for the maximum effect of the anesthesia to be reached. Some patients report that the application of the implant area is a little more annoying than that of the donor area. However, once it takes effect no pain is felt.
Contraindications and risks of anesthesia.
When the procedure is performed by an expert surgeon, the risks and complications are minimal. However there are some issues that need to be considered.
One of the most frequent adverse reactions is the formation of bruising or bruising after anesthesia. It is important to avoid the use of anti-inflammatories such as aspirin the days before the procedure.
Direct injection of anesthesia into the bloodstream should be avoided. This is avoided by light sucking to check that the needle is not inside a blood vessel.
Intra-nervous injection or nerve damage
It is very rare. It can happen when an unexpected movement of the patient changes the angulation of the needle when infiltrating the anesthesia.
As local anesthesia the risk of overdose is very low, however all doses should be calculated taking into account the weight of the patient.
They are extremely rare. The intensity of the reaction depends on the dose used. It is slightly more likely in asthmatic patients.
The use of vaso-restrictors should be avoided in patients who have untreated hypertension or recent myocardial infarction, severe bradycardia, atrioventricular block, or under treatment with antiarrhythmic drugs such as amiodarone.
General anesthesia for hair implant.
Generally, this type of anesthesia is not recommended due to the risks related to this type of anesthesia. However, it can be considered in some patients under the supervision of an anesthesiologist.
